The first Swahili language PLA users guide in Tanzania was developed in Ngorongoro by two practitioners whilst providing training to Ereto 1 staff, customary leaders, local government and women on how to use and develop PLA (participatory learning and action) tools. PLA tools and approaches were developed to specifically accommodate and explain mobility within the pastoralist livelihood systems. The main PLA tools developed are to enable communities and Ereto staff to explain and analyse situations and issues using local terms and available materials, and minimising written words. This allows illiterate members of the community to contribute their valuable insights. The tools helped explain current and historical gender roles, water use and strategic water development, livestock diseases, weather patterns, work patterns, power relations, institutional arrangements and much more. The tools help community members to identify the direction and dynamics of pastoralist livelihoods, and empower community members and project staff to identify issues and develop planned interventions.
